From Just Solve the File Format Problem

APK is an archive format used for distributing Android apps. It is based on the Jar format (for Java), and like that format, is actually a ZIP archive with a different extension, and with specific files and directories within it.
Metadata about the app is in a META-INF directory within the archive (similarly to Jar files), compiled code is in a lib directory, and resources in a res directory. There are also a few files at the root level including AndroidManifest.xml (which may be regular XML or, often, binary XML).
